I have used this barrel for about 3 months and it has yet to break a ball. The adjustment feature on the top is great for selecting the distances at which you want to shot. You can shoot with zero flatline effect and its every accurate at short range. The only problem is its loud with the minimal porting which is only in the middle of the barrel. I would recommend this to anyone over the flatline because it is easier to clean and maintain on the feild and has more feature to keep you happy.

Conclusion:

You want a highly versitile barrel with the ability to be able to shoot 200 yard and still break and be accuate. Or a barrel that can curve around or over bunkers will then you found it!!!!
